[Linuxvm-dev] first stab at email comparison

[Matthew J. D. <mda...@se...>]

This is the code I wrote to identify unique memebers of a hash.

Hash one could be the messages in email and hash2 the messages in the
voicemail.

We want to know the unique ones so we can delete them.

#!/usr/bin/perl -w

use strict;

my %hash1 = (
            field1      => "1",
            field2      => "32",
            field3      => "4",
            field4      => "5",
            field5      => "434",
            field6      => "43"
);

my %hash2 = (
            field1      => "1",
            field2      => "2",
            field3      => "3",
            field4      => "4"
);

for (keys %hash1) {
     my $nomatch = 'true';
     my $val1 = $hash1{$_};
     for (keys %hash2) {
         my $val2 = $hash2{$_};
         if ($val1 eq $val2) {
         $nomatch = 'false';
         }
     }
     if ($nomatch eq 'true') {
     print "$val1 is unique from hash2\n";
     }
}

print "\n";

for (keys %hash2) {
     my $nomatch = 'true';
     my $val1 = $hash2{$_};
     for (keys %hash1) {
         my $val2 = $hash1{$_};
         if ($val1 eq $val2) {
         $nomatch = 'false';
         }
     }
     if ($nomatch eq 'true') {
     print "$val1 is unique from hash1\n";
     }
}
